摘要
研究神经网络技术在弧焊机器人焊缝跟踪过程中的应用,通过神经网络在笛卡尔空间轨迹的补偿作用,确定出基于笛卡尔空间参考轨迹控制的机器人焊缝跟踪神经网络控制器。与传统的关节计算力矩法相比,所设计的神经网络控制器具有良好的控制特性及较强的鲁棒性,焊缝跟踪精度得到了显著的提高。
The application of neural network technique in the seam tracking process of arc - welding robot is studied. A neural network controller to modify the reference Cartesian trajectory for the robotic seam tracking is presented through the compensation of the neural network for the Cartesian trajectory. Compared with the traditional computed torque control method, the proposed neural network controller yields salient controlling characteristics and strong robustness. The precision of seam tracking is conspicuously promoted.
